Question

I am trying to set up and use the debugger in RubyMine 4. I am running Rails 3.2, Ruby 1.9.3-p125 OS X. I have the proper gems, and can set breakpoints, set up a configuration, etc. But I am unsure of the workflow.

I am looking for a pointer to some documentation on how to actually use the debugger. Links? Screencast? Tutorial? Once I get going, I’ll be all set.

(Edit, clarified my actual question).

How to debug a Rails application:

1. Place a breakpoint somewhere in the app code
2. Create Rails Server Run/Debug configuration (or use the existing one if the project was created in RubyMine)
3. Click on the Debug button in the toolbar
4. Rails server starts in debug mode
5. Browser with the app opens (or you open it manually if such option was disabled)
6. Navigate to the page that will trigger breakpoint
7. Observe the stack frame, locals, etc in the RubyMine Debugger pannel.
